The present invention is a continuation of application Ser. No. 09/542,010, filed Apr. 3, 2000, now U.S. Pat. No. 6,606,754, which claims priority to provisional application 60/128,433, filed on Mar. 30, 1999.
The present invention relates to a pad that provides hypo/hyperthermia properties to a person using the pad.
In U.S. Pat. No. 5,336,708, Chen discloses a gelatinous elastomer composite article. These articles, as disclosed by Chen, “include: GMG, MGM, MG1G2M, M1M2G1G2, M2M1G1G2, G1MG1G2, MG1G2, G1G2M, G2G1M, GM1M2G, G1M1G2M2M1, M1GM2GM3GM4, [sic] ect, where G=gel and M=material. The subscript 1, 2, 3, and 4 are different and are represented by n which is a positive number. The material (M) suitable for forming composite articles with the gelatinous elastomer compositions can include foam, plastic fabric, metal, concrete, wood, wire screen, refractory material, glass, synthetic resin, synthetic fibers, and the like. Sandwiches of gel/material . . . are ideal for use as shock absorbers, acoustical isolators, vibration dampers, vibration isolators and wrappers. For example the vibration isolators can be [sic] use under research microscopes, office equipment, tables, and the like to remove background vibrations.” U.S. Pat. No. 5,336,708, col. 3, lines 35-51. Chen further discloses, “generally the molten gelatinous elastomer composition will adhere sufficiently to certain plastics (e.g., acrylic, ethylene copolymers, nylon, polybutylene, polycarbonate, polystyrene, polyester, polyethylene, polypropylene, styrene copolymers, and the like) provided the temperature of the molten gelatinous elastomer composition is [sic] sufficient high to fuse or nearly fuse with the plastic. In order to obtain sufficient adhesion to glass, ceramics, or certain metals, sufficient temperature is also required (e.g., above 250° F. [121° C.]).” U.S. Pat. No. 5,336,708, col. 9, lines 8-18 (brackets added for consistency of temperature comparison).
Elkins in U.S. Pat. No. 4,884,304 describes a bedding system with selective heating and cooling of a person. That system has, from top to bottom, in order: a top mattress cover, a gas envelope and a multiplicity of liquid flow channels. The multiplicity of liquid flow channels is accomplished by a conventional hypo/hyperthermia blanket. The details of this conventional blanket are set forth in this patent. A problem with this system occurs when a person is on the mattress cover. When the person is on that mattress cover, the person has two sides: (1) a “contacting side” that touches the mattress cover and (2) the “exposed side” that does not touch the mattress cover. The person disperses the gas-envelope and only certain portions of the contacting side contact the flow channels. As shown in FIG. 5 of that patent, the shoulders and other peripheral points of the contacting side of the person, such as arms, do not contact the flow channels. Thereby, that bedding system fails to transfer the desired temperature of the flow channels uniformly to all sections of the contacting side of the person.
M. Figman in U.S. Pat. No. 3,266,064, and von der Heyde in U.S. Pat. No. 5,887,304 illustrate conventional convective medium mattress system which essentially has a lower “box spring” and a mattress made of rubber, foam, or conventional mattress materials that an individual or object lies thereon. In each embodiment, the lower box spring has a cavity that the medium enters and distributes throughout. The medium then escapes from the cavity through apertures of the mattress.
A problem with these apertures 89 is that they kink 90 when an adult lies 22 thereon, as shown in FIG. 8. Please note that von der Heyde's system is designed for an infant, not an adult. And an infant is of such low weight that kinking is essentially nonexistent.
When kinking occurs, the medium is prevented from contacting the body. And when the medium does not contact the body, the medium is unable to treat the hypothermia or hyperthermia portions of the patient that contact the mattress, or even cool or heat the portions of the patient that contact the mattress.
The present invention solves this problem.
The present invention relates to a first conformable material having a three-dimensional shape and a first hypothermia and/or hyperthermia device.
A preferred embodiment of the present invention is described in detail hereinafter with reference to the accompanying drawing, in which:
The conformable material 18 is any material having apertures that do not easily kink, preferably, a gelatinous elastomeric material. Examples of types of gelatinous materials, which are heat formable and heat reversible, are fully described in U.S. Pat. Nos. 4,369,284, 4,618,213, 5,262,468, 5,336,708, and 5,508,334, which are hereby incorporated by reference herein, and those made by Pittsburgh Plastic. The gelatinous materials manufactured by Pittsburgh Plastic are allegedly distinct from the patented types. This conformable material can be of any shape or design, so long as it has a three-dimensional shape that supports a patient or object on the pad 10.
The hypothermia and/or hyperthermia device 14 is any conventional hypo/hyperthermia blanket—an example of this blanket is the MUL-T-PADŽ or the THERMACAREŽ blanket by Gaymar Industries, Inc. of Orchard Park, N.Y.—and its corresponding pump—the MEDI-THERM IIŽ temperature regulator by Gaymar Industries, Inc. of Orchard Park, N.Y.—, an electric blanket, a cold compress, and a convective device. The convective device pumps or blows air or other gaseous medium (collectively “Air”) having a predetermined temperature. The Air obtains the desired temperature in a conventional Air temperature regulator (for example, an air conditioner, a heat pump, a ThermaCareŽ blower unit, or the MEDI-THERM IIŽ temperature regulator) and then circulates through a mesh screen like the Air Queen by Teijin, Inc. or a non-woven polymeric device having a plurality, of tubes with numerous apertures therein. The Air is then distributed throughout the entire pad 10. In any embodiment of device 14, the device 14 affects the temperature that a patient (not shown) or object (not shown) is exposed to, and, in some embodiments, the medium 20 that encompasses the conformable material 18.
The bag 12 is any sealable instrument that contains at least the thermally conductive medium 20 and conformable material 18 in place. Preferably, the bag 12 is plastic, and it can be sealed thermally, acoustically, by a zipper, zip locked, or even by VelcroŽ.
The pad cover 16 is any conventional material used to cover a pad 10. The pad cover 16 can encompass the entire pad 10, the preferred embodiment as shown, or cover the pad 10 like a conventional mattress sheet. In either embodiment the pad cover 16 can be cloth, leather, plastic or conventional cover material. The materials of the pad cover 16 allow the patient or object, on the pad 10, to feel the desired temperature of the pad 10 (Air or medium 20). The pad cover 16 can also allow moisture to pass through it. Thereby, it helps control the patient's temperature and prevents overcooling or overheating.
In a preferred embodiment, the conformable material 18 has apertures 24. The apertures 24, in this embodiment, go from the bottom to the top of the material 18 and ensure the thermal conductive medium 20 is between the patient 22 and the hypothermia and/or hyperthermia device 14. However, in order to decrease, and essentially avoid, kinking—which is discussed above and, as a reminder, inhibits the medium 20 or the Air from contacting the patient—and which is common in many mattress materials, the preferred embodiment of the conformable material 18 is a gelantinous elastomer material. The gelantinous elastomer material has a structure design that admittedly bends and indents, as shown in
The hypothermia and/or hyperthermia device 14 heats or cools the thermal conductive material 20 and the patient 22 to a predetermined temperature. Since the thermal conductive material 20 contacts most, if not all, portions of the contacting side 23 of the patient 22, the material 20 ensures a uniform, or nearly uniform application of the predetermined temperature to the contacting side 23.
In one embodiment (like that shown in
Alternatively, the pad cover 16 has a material that transfers the temperature to the patient but influences the Air to a predetermined gap(s) 345 in the pad 10. The predetermined gap(s) 345 can be located anywhere within the pad, i.e. at the bottom of the pad, a side of the pad as shown in
Turning to the method of the invention the preferred embodiment of the present invention is as an operating table pad and/or any other structure or object used in an operating room or hospital-like mattress system, such as bed systems or seat cushions. An operating technician inserts at least one pad 10, having a hypothermia and/or hyperthermia device 14, and a conformable material 18, under a predetermined area of a patient 22. The technician then adjusts the device 14 to a predetermined temperature, in some instances the device 14 can only obtain one temperature. In either case, the device 14 adjusts the pad 10 to the predetermined temperature. At any time before or after the device 14 is initially adjusted to the predetermined temperature, the patient 22 lies on the pad 10 and the contacting side 23 of the patient 22 will be or is exposed to the predetermined temperature.
Although a particular preferred embodiment of the invention has been illustrated and described in detail for illustrative purposes, it will be recognized that variations or modifications of the disclosed apparatus, including the rearrangement of parts, lie within the scope of the invention defined by the claims.
